The first extermination camp was Chelmno, located In Lodz, Poland. Approximately 153,000 Jews and other people were killed there. In 1943, the camp was torn down and burned, all prisoners that were left were sent to Auschwitz-Birkenau.
Auscwitz-Birkenau
Regular Jews were not the only ones targeted in the concentration camps. In Auschwitz, Doctor Joseph Mengele would pick out twins and other people with hereditary differences for experiments. The twins were treated with care and were given food and got to keep their clothes and hair. Until they were taken for experiments, the twins did not have to suffer like the other Jews. One experiment was to fabricate blue eyes, drops or injections of chemicals would be put in the eyes. This often caused severe pain, infections, and temporary or permanent blindness. Everyday, all twins had to have blood drawn. Blood, often in large quantities, was drawn from twins fingers and arms, and sometimes both their arms simultaneously. The youngest children, whose arms and hands were very small, suffered the most. Blood was drawn from their necks, a painful and frightening procedure. It was estimated that approximately ten cubic centimeters of blood was drawn daily.
